Whats the differance?

The spur is a Mod1.

The Traxxas nitro rear wheels are the same offset as the electric front wheels. They have a wider offset than the electric rear wheels. So, for a wider track width, use the electric fronts or nitro rears. Also, if you really want something that looks sharp, check into the new Pro-Line 30 Series Torque NItro Rears and a set of 30 series Dirt Hawgs. The Dirt Hawgs are only 4" in diameter and would look killer on a CRT.5
